Has anyone here ever tried learning Esperanto to help in their language studies?

[Ideas]

Not that I entirely disagree, but Esperanto can be learned very quickly compared to other languages, which I assume is what the basis of the springboard argument is. In a study, students that spent a year studying Esperanto and three years studying French were more proficient than students who studied no Esperanto and studied four years of French.

I'd be curious for my situation. I've studied Spanish on and off, but let's say it's 1 year of Spanish. I'm not sure if I would be better off studying Esperanto for a year and Spanish for 2 years, in terms of Spanish skills. (I think I'd be better off studying Spanish for 3 years.) But at least I'd know Esperanto.
